Applicatien filed June 16,

vTo all whomit may concern:

Be it known that I, FRED O. LAKE, a jciti zen' of the United States, residing at VVashington,"in the District of Columbia, have invented certain new and useful Improvements 1H. l llCaIl1Z1Ilg T0Ilg$, of whlch the following is a specification.

This invention relates to tools and implements for vulcanizing purposes, and pertains especially to an implement particularly adapted forpatchwvulcanizing through the medium of an ordinary pan or tray. having the patch attached thereto and containing an inflammable element.

a tong-like implement of novel and peculiar design. specially constructed for applying rubber patches and for clamping the same in proper "position during vulcanization.

A further obj ect of the invention is to pro- ,vide a hand implement inthe shape of pliers or tongs which shall have such construction and combination of parts as to retain and to operate in. connection with rubber patches and patch holders of various size and shape for vulcanizing the same. i

A still further object of the invention is to providea simple, inexpensive implement of such strength and durability'as will afford .means for expeditiously repairing and vul-.

can zing tire and other patches in a most convenient manner, and'with such perfection as to be substantiallyipermanent.

As far'as known to applicant, such devices and' apparatus usually comprise a special gas or oil burner member, ananvil member, and various mechanism for clamp-V ing the punctured or torn tire portion and the patch therebetween. In addition to the weight and cumbersome condition of such devices and apparatus, they comprise a multiplicity of parts requiring separate and repeated manipulationin their application and operation. It is the purpose of this invention to overcome the disadvantages and difficulties found in such device and apparatus and to avoid the usual imperfect and unsatisfactory results usually experienced in tire and other patching and to furnish an implement complete in itself and without contributory mechanism or devices for its operation in connection with a patch tray or pan containing inflammable material. To these ends, the. invention consists in the novel and peculiar eonstruction and arrange- ,Spe'cification of Letterslatent'.

The same reference characters denote the same parts throughout the several views of the drawings. The tray or pan 1, is of common form, and the inflammable paper pad or sheet 2, conand has 'a patch 3 attached to the bottom tray 1, and of such size as to accommodate The tong-member 5.

The legs are preferably struck or formed out. of or in the same piece with the head or jaw .10, and each of said; legs is provided with a lateral projection constituting a clamping foot 12. Each foot has a plurality of shoulders or seats 13 corresponding with "the various sizes of pans applicable thereto.

so that the rim of the pans may fit one or another of the seats and-thereby centralize the pan with respect to the headsor jaws 9 and 10, in a clamping orvulcanizing operation. Said seats also retain the trays with a patch in proper position as placed over a tire or other article as 1* Fig. 5 is a perspective view of a further" I t ained in the tray, is of the usual character, i f thereof as usual. The tong members 4 and a 7 and 8 respectively. The tongto be patched and and to prevent the opening thereof without pressing the tongue inwardl prevent the feet from slipping rim during a clamping an operation. 4-

In order tosedure the tong-members in clamped position, I provide a locking device which consists of a spring tongue 14 proje'eting at right anglesfrom the handle portion 7, and 'in'sertible through a slot 15 inthe end 'of the other handle po'rtion 8. Said tongue having teeth or corrugations 1,6, for

Referringto the modification shown'in Fig 4 of the drawings, the pronged head 22 1s. sw yeled at 23, tofthe end of the tong-- member =24, and the feet 25 have seats'26,

and shoulders 27 which set in under the seats, for clamping trays of various: shapes Obviously other variations pronged ;or legged head, and in the feet, may bemade. in the development of the device.

It will be understood that in a vulcani zing patched, is placed upon the plate-head, the tray containing the paper pad and'the patch is placed upon] the tire or article,the tongmembers are locked in clamped position, and
